Preheat your oven to 400°F and line a baking sheet with parchment paper.
Pat the chicken wings completely dry with paper towels to ensure maximum crispiness.
In a large bowl, toss the wings with avocado oil, sea salt, black pepper, garlic powder, and smoked paprika until evenly coated.
Arrange the wings in a single layer on the prepared baking sheet, leaving space between each piece.
Bake for 35-40 minutes, flipping halfway through, until the skin is golden brown and crispy.
While the wings bake, whisk together the sugar-free BBQ sauce and hot sauce in a small bowl.
Remove the wings from the oven and toss them in the spicy BBQ glaze until fully coated.
Return the wings to the oven for an additional 2-3 minutes to allow the glaze to become tacky and caramelized.
Serve immediately with fresh celery sticks on the side.
